Nicotine (CAS 54-11-5)
Nicotine (CAS 54-11-5)
Nicotine is the substance in tobacco, nicotine content of tobacco because there are different species and origin, alkali content of tobacco each part is different. Cigarette factory scraps (tobacco powder) containing about 1% to 2% of the nicotine, tobacco stems and ribs smoke nicotine containing about 1% or so, people smoked cigarette contains nicotine amounted to about 3%. Pure nicotine is a colorless, oily liquid, miscible with water below 60 ℃, hydrate, more than 210 ℃ also miscible with water. Unstable nature, likely to be volatile, soluble in water and organic solvents. Nicotine is an alkaloid, so all properties of a base, to a compound made of salts and acids. In case of light and air turn brown and sticky, there is the odd smell and strong irritant.

Nigrosin (CAS 101357-16-8)
Nigrosin (CAS 101357-16-8)
In staining dyes, nigrosin (CI 50415, Solvent black 5) is a mixture of black synthetic dyes made by heating a mixture of nitrobenzene, aniline, and hydrochloric acid in the presence of copper or iron. Related to induline, it is a mixture of phenazine-based compounds. Its main industrial uses are as a colorant for lacquers and varnishes and in marker pen inks. Sulfonation of nigrosin yields a water-soluble anionic dye, nigrosin WS (CI 50420, Acid black 2).
Aside from its main use in lacquers, small amounts of nigrosin are used for negative staining of bacteria. as well as the capsule-containing fungus Cryptococcus neoformans. The shapes and sizes of the organisms are seen as color-free outlines against the dark background. An advantage of using this method, rather than regular positive stains like methylene blue or carbol fuchsin, is that prior fixation by heat or alcohol is not needed, so the organisms are seen in more lifelike shapes. Furthermore, negative staining with nigrosin can reveal some microorganisms that cannot be stained by regular methods. Nigrosin WS is used in tests for viability because living cells exclude the dye, but it enters dead cells
Nitric acid 56-58% (CAS 7697-37-2)
The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as red fuming nitric acid at concentrations above 86%, or white fuming nitric acid at concentrations above 95%.
Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.

Nitro Thinner 646
Nitro solvent 646 is a classic nitro solvent. Introducing a mixture of various volatile organic liquids (6 components). The original recipe has a ten-year history and has established itself as the most versatile and high-quality composition with excellent properties. Unfortunately now in Europe you will not find a 100% original composition anywhere, as some components are prohibited for circulation in the European Union. Our recipe preserves all the best properties of this product due to the fact that we have replaced the prohibited components with new generation products that are more environmentally friendly. MasterChem has been manufacturing this solvent directly for 25 years. Nitro solvent is a colorless or slightly yellowish liquid with a characteristic odor. It is used in production and in everyday life for diluting and bringing paints and varnishes to a working consistency. If you want to become a sales representative of our product, we are open to negotiations.
Nitroethane (CAS 79-24-3)
Nitroethane (CAS 79-24-3)
Nitroethane is an organic compound having the chemical formula C2H5NO2. Similar in many regards to nitromethane, nitroethane is an oily liquid at standard temperature and pressure. Pure nitroethane is colorless and has a fruity odor.
Via condensations like the Henry reaction, nitroethane converts to several compounds of commercial interest. Condensation with 3,4-dimethoxybenzaldehyde affords the precursor to the antihypertensive drug methyldopa; condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene. Nitroethane condenses with two equivalents of formaldehyde to give, after hydrogenation, 2-amino-2-methyl-1,3-propanediol, which in turn condenses with oleic acid to give an oxazoline, which protonates to give a cationic surfactant.
